I picked up a pair of "toy" video walkie talkies with front and rear cameras for $20. I absolutely cannot believe the quality of the video (full motion, virtually no lag) and the range (300 meters outside? More? Not at all bad inside either) and the audio is completely acceptable. I had read that some of these units recorded each utterance push-to-talk and then sent it over complete to the other unit -- but these are sending audio on the push-to-talk in real time with almost no delay. Units pair to each other, apparently using 2.4 Ghz encrypted, presumably ad hoc network. $20 for a pair. This is nuts.
